I know this is a bit roundabout, but I could not find ANYWHERE to buy a push on angle valve with a 1/4 inch compression output, which is why I wound up with Steps 3 and 4.

This setup works 99%. The two push-on fittings (Steps 1 and 2) are holding perfectly well with absolutely no leak.

The connection between Steps 2-3 and 4-5 are also tight with no leaks.

My only problem is the connection between Steps 3-4, where the braided "faucet supply" connects to the 3/8 inch end of the Watts adapter. I have tightened it and used some teflon tape but there remains a very teeny tiny leak. As in, a single water droplet at random intervals, maybe a handful per minute. I've redone the connection several times but the single droplet problem remains.

Looking for both ideas on why this is happening and is there a clever solution to suppress the single occasional water droplet leak, that isn't a gusher or even a steady trickle?

I had a similar problem and fixed it by adding about 4 extra windings of teflon tape... I'm not an expert so I may wrong as far as professional installation goes but it worked for a simple DIY for me...

If you have what I think, both of those hoses normally have a gasket in the end, and the use of tape can cause a leak. The gasket against the ball end of the fitting should seal fine on their own. Also, overtightening them can be a problem.

I have read that about the flood prevention devices. But no, the only Watts piece in this assembly is a very simple 3/8 inch to 1/4 inch brass adapter, threaded male at both ends. The "faucet hose" is just your standard commonplace kind.

Our pleasure! I checked my email via our remote server and didn't see an email enquiry from you. Sometimes our mail server quarantines items. If you don't have a reply to your email by 10:00 am EST, then you may want to give them a call at 1-800-268-2363. Just press 1 when you hear the company greeting and you'll be routed to the Customer Service Dept. Tell them what we've discussed and they'll look after you. I'm on vacation...sort of ...they have direct access to me all week even though I'm not there.

Mr. Dahl, can you post a link to your companys products? I like to buy American, but you Canadians are a good second choice. I saw your valves in a seperate post by Ian and they looked like a good piece of work.

Our website is here: www.dahlvalve.com. We have some work to do on our website so our Product Search function is somewhat outdated and the best information is on the Downloads page or uisng the "Build Your Own Mini-Ball Valve" function (if you need something unusual).

Dahl qualifies for projects with Buy American requirements under the ARRA because we buy so much of our raw material in the U.S.A. That valve in the photo you saw in the other thread is made from American brass. Dahl is not simply an assembly plant - we design, engineer, machine, assemble, test, package & ship the finished product from our one location outside of Toronto.

We sell to a number of supply houses in California. Your best bet is to find the local Dahl rep (on our website Sales Agencies link) and have them recommend a supplier in your area. You are also most welcome to contact our office directly.
